The following 366 words (one extra for leap years) are used in the various Vocabulary Quizzes of this guide. They are also purported to be used frequently in Scholastic Aptitude Tests and Graduate Record Exams, and you might want to use this list to help study for those exams. The list here is by no means a complete list of words that you might run across in either the SAT or the GRE, however. Also, the words are not listed in any particular order; this is not a dictionary and is not designed to be used as one. Click on each word's button and a definition and a sample sentence will pop up. Try to define and use the word yourself before clicking on the button. Close each window before going on to another word by clicking on the "OK" button.
